So far the plan for September is everyone is back in class 100%. If there is an outbreak then the sister/family of schools would be targeted for closure, not the entire school system, which makes sense. High school students need to wear masks in the hallways, etc but not in class. This made me think of the Junior Highs that also change classes. But I would agree with you
@hdrolfe that the teachers could move to the class instead. Each teacher would have to wipe down the desk, whiteboard and accessories, etc.
I had DD out shopping for some fall clothes and man, I forgot how expensive everything is now!
